Perl uses the @INC array to determine the directories where modules
reside.  If the Koha modules are in a directory outside of the normal
perl @INC, perl will not find them.

There are several workarounds:

  1. Invoke perl with a parameter specifying additional directories to
     search in:

       perl -I path/to/C4

  2. Alter the fines2.pl script to push onto @INC:

       push @INC, 'path/to/C4';

  3. Set up symlinks from your Koha module directory into your normal
     perl path.

       perl -e 'print join("\n", @INC, "")'
       ln -s /full/path/to/C4 path/to/site_perl/C4

Hope that helps.
